开启usb主机功能

&usbhost_dwc3 { // phys = <&u2phy0_host>; // phy-names = “usb2-phy”; // maximum-speed = “high-speed”; // snps,dis_u2_susphy_quirk; status = “okay”; };

&combphy1_usq { // rockchip,dis-u3otg1-port; status = “okay”; };

&usbhost30 { status = “okay”; };

SDIO接口的电源序列控制

可用于WiFi信号

	sdio-pwrseq {
		wifi_enable_h: wifi-enable-h {
			rockchip,pins = <2 RK_PB1 RK_FUNC_GPIO &pcfg_pull_none>;
			//WIFI_REG_ON_H_GPIO2_B1
		};
	};
